The AEM Engine Management System (EMS) is the result of extensive development on a
wide variety of vehicles. Each system is engineered for a particular application. The AEM
EMS differs from all others in several ways. The EMS is a “stand-alone”, which completely
replaces the factory ECU and features unique plug and play technology. There is no need
to modify the factory wiring harness and in most cases the vehicle may be returned to
stock in a matter of minutes. The AEMPro software is configured to work with the factory
sensors and equipment, so there is no need for expensive or hard to find sensors, making
replacements and repairs as simple as with any stock vehicle. For stock and slightly
modified vehicles, the AEMPro software can be programmed with base parameters,
providing a solid starting point for beginner tuning. For more heavily modified cars, the
EMS has many spare inputs and outputs allowing the elimination of add-on rev-limiters,
boost controllers, nitrous controllers, fuel computers, etc. It will also allow programmable
control over all automatic transmission functions, and includes a configurable onboard
data logger capable of recording 512kb of information. Every EMS comes with all
functions installed and activated and there are no options or upgrades to be purchased.
